BENCH-VISE.

Specification of Letters Patent.

Patented Nov. 21, 1905.

To cbll'wwm, it may concern:

Be it known that I, CHARLES HANIMANN, a citizen of the United States,residing at Flushing, in the county of Queens and State of New York,have invented certain new and useful Improvements in Bench -Vises, ofwhich the following is a full, clear, and exact specification, referencebeing had to the accompanying drawings and to the reference charactersmarked thereon.

My present invention has relation to vises such as are employed bymechanics and others and intended to hold articles or materials whilethey are being worked upon. These vises are usually attached to-someiixed sup port, as a bench or table, and they are ordinarily known asbench-vises. Of these bench-vises there are many varieties suitable forholding different kinds of work and operative in different ways, and itis chiefly to a variety now come to be commonly known as swivel-bottomvises that my invention is principally applicable, although some of thefeatures are equally applicable in connection with other varieties,aswill hereinafter appear.

The principal object of my invention is to provide or produce aswivel-bottom or turning vise wherein the clamping` or setting of thevise-body at the desired point upon the base may be conveniently andsecurely accomplished by the act of turning the vise-screw, the basebeing grasped by the holding mechanism on opposite sides of the exteriorof the cylindrical part on which the vise-body turns, thereby affordingan extensible leverage for the holding mechanism against any disturbingaction, the parts being simple, cheap, and

easy to make and effective in action or results.

A subordinate object is to provide means for easily setting the clampingmechanism so that it will not clamp the base, but will leave thevise-body free to be turned on its base whenever so desired.

Another object of the invention is to provide a simple, cheap, andeffective means for locking and holding a turning or adjustable back jawof a vise accurately and securely in position parallel with the frontjaw when it is intended that the former shall remain stationary withrespect to the latter.

To accomplish the foregoing objects and to secure other and furtheradvantages in the matters of construction, operation, application, anduse, my improvements involve certain new and useful peculiarities ofconstruction, relative arrangements or combinations of parts, andprinciples of operation, as will be herein first fully described andthen pointed out in the claims.

ln the accompanying drawings, forming part of this specification, I haveshown my improvements as applied in connection with a particular form ofbench-vise which is ordinarily called a smiths vise or cmetalworkersvise; but it should be understood that this selection is only forconvenience of illustration and that my improvements are equallyapplicable in connection with any other variety of bench-vise.

Figure l is a vertical view, partly in section and partly in elevation,on a plane through the axis of the vise-screw, showing my improvementsapplied in connection with a swivel-bottom vise, wherein a rack and dogor pawl are employed for operation in conjunction with the screw-shaftin order to force or release the slide-bar. Fig. 2 is a horizontal view,partly in plan and partly in section, showing the base and the meansemployed for securing the vise-body thereon so as to turn upon theexterior thereof and means for freeing the clamping mechanism. Fig, 3 isa plan of a separate piece employed in connection with the rear of thevise-body and the base, the same being detached from the other parts.lFig. 4 is a central vertical section and elevation corresponding withFig. 3. Fig. 5 is a vertical view, partly in section and partly inelevation, showing the base and a fragment of the vise-body appliedthereon, the view being taken on a plane through the axis of anadjustable clamp applied in connection with the viseebody. Fig. 6 is asectional elevation on a scale enlarged beyond Fig. 5, showing the'adjustable cla-mp represented in that figure. Fig. 7 is a side view andpartial section of the rack shown in Fig. l, the same being detached.

Fig. 8 is a horizontal section and plan View on a plane through the axisof the screw-setter for the swiveled or movable jaw of the vise. Fig. 9is an elevation on a smaller scale, showing the plate by which thescrew-setter for the .movable jaw is held in working position inconnection with the vise-body. Fig. l0 is a view, partly in section andpartly in elevation, corresponding with Fig. l, except that a nut withinthe vise-body is employed to receive the vise-screw and to cause themove- IOO IOS

ments of the slide-bar and the vise-head, connected therewithdirectly'through the medium of the vise-screw and operating to clamp thebase at one part. Fig. 11 is a view in crosssection illustrating themanner of mounting the nut shown in Fig. l0 in the vise-body, and Fig.12 is a side view of the nut detached.

In all the figures like letters of reference wherever they occurindicate corresponding parts.

The vise shown in Fig. 1 is of the rapidtransit or quick-actionvariety-that is, it is arranged so that when the screw-shaft A is turnedin one direction the dog or pawl a will be engaged with the rack B andthe slide-bar carrying the movable head C then forced in a direction toclose the head C toward the stationary7 head D, and when the screw-shaftis turned in the opposite direction the dog or pawl a will rise out ofengagement with the rack, and thus leave the slide-bar free to bequickly moved back and forth for rapid adjustment without the necessityof turning the screw. This in itself is an old form of construction orarrangement and is not an essential part of my present invention,although it or any other form of connection between the slide-bar, thevise-body, and the screw-shaft maybe adopted. For instance, in Fig. 1()the screw-shaft A engages with a nut B, applied in connection with thevise-bod y, and the slidebar is to be slowly moved in either directionby the turning of the screw-shaft. The rack or the nut equally receivesthe thrust of the vise-screw.

E represents the base on which the visebody is mounted and which isintended to be secured to a bench or table or other support in anysuitable way or by any suitable means. The vise-body is mounted so as toturn upon the exterior of this base and so arranged` and connected withthe base that whenever the vise-jaws are tightly closed together orforced against a piece of work or material between them the vise-bodywill become effectually clamped at opposite parts against the outside ofthe stationary base, thereby being held securely in the position wherethus clamped in order to prevent movement upon the base while the viseis in use. As soon as the visejaw or vise-screw is loosened after theparts have been clamped the vise-body will be free to turn unless set orfixed in place by separate and independent means, which separate andindependent means are provided for use in case it be desired to so setthe vise-body.

To make the automatic clamping rigid and secure, I provide the base withan annular recess 7) around its exterior, and I supply the front part ofthe vise-body with a corresponding annular ledge c, reaching about halfthe circumference of the circle and adapted to fit closely in the recessWhen the rack is employed to receive the th rust of the vise-screw, Isupply the same with a depending portion d, having an inwardlyprojecting ledge e, also calculated to move in the recess This rack isadjusted in the body of the vise from the rear and is secured in placeby a suitable screw-bolt or other equivalent means, as f, the samepermitting a very slight movement of the rack in its seat for reasonsto'be hereinafter explained.

When a nut B is employed to take the thrust of the vise-screw, it ismounted in the vise-body in a manner similar to the mounting of the rackand it is supplied with a depending portion, as CZ, having an innerledge e', also adapted to fit in the recess b, and the nut is secured inplace by a screw-bolt, as f, or by equivalent means, this fasteningpermitting a very slight movement of the nut on its seat, the same asprovided for in the case of the screw-rack.

At the rear of the vise the body is extended, as at g g, and upon thisextension is secured a curved piece, as F, having a ledge c2, alsocalculated to lit in the recess b. This piece F is secured in place bysuitable screws or bolts, as at the points /L z, and when in place itoperates for one purpose to extend or lengthen the bearings in therecess opposite the front of the vise. This piece F is employed equallywhen a rack or a nut is used.

The parts being constructed as so far explained, it will be apparentthat when the vise-screw is turned in the direction to move one jawtoward the other the front bearing part of the vise-body will beforcibly crowded to its seating on the outside of one part of the baseand the rack or the nut forcibly clamped against the outside of theopposite part of the base, thereby efect-ually clamping and holding thevise-body at the point at which the clamping of the work takes place.The clamping being effected upon the exterior of the base, a longleverage is afforded for resistance to any possible turning action ofthe vise-body by reason of which the clamping is made entirely effectiveand not liable to slip or give way under any ordinary circumstances ofuse.

The clamping is automatically effected, as will be observed, and theopposite turning of the vise-screw will loosen the parts sufiiciently sothat the vise-bod y may then be easily turned on its seat on the base.At times it may be desired that this automatic clamping of the vise-bodyshall not be effected, and I therefore provide means by which it may beprevented. As previously explained, the rack or the nut is capable of aVery small movement on its seat in the vise-body. Through the piece F, Ipass a suitable screw-bolt, as ri, and this enters and engages thedepending portion of the rack B orthe nut B', as the case may be. Byturning this screw in the proper' direction the rack or the nut is drawntoward the piece F through a very slight distance, suiiicient, however,to yprevent clamping against the base-piece in connection with the frontpart of the vise-body. By this means the parts may be so adjusted andset that the automatic clamping will not be effected, or after theclamping has been effected the parts may be loosened, so that thevisebody may be easily turned on its base, if so required, and withoutdisturbing the visescrew. To provide means independent of the vise-screwfor setting or fixing the vise-body at any desired point on its base, Isupply the upper part of the base with a series of teeth or serrations,as at and on the front part of the vise-body and at a convenient point Iprovide a socket, as G, which receives a screw G', on the lower end ofwhich is mount# ed a loose block G2, having teeth or serrations adaptedto engage with or interlock with those at 70. When the screw Gr isturned up, the visesbody, if otherwise free to be turned on its base, isin no mannerinterfered with; but when the screw G is turned down thevise-body will be set, and this setting may take place at any point ofthe circular travel of the vise on its base. This particular means ofsetting the vise-body is only employed as an example, it in itself beingold, and it may be replaced by any other equivalent means foraccomplishing the setting.

The back jaw D is of the swiveled varietythat is, it is mounted on thevise-body so that it may turn to accommodate itself to the side of anyinclined or irregular piece of work or material; but the swiveled jaw isnot necessarily employed in connection with a vise structure arranged tobe clamped upon its base after the manner of my invention, as aboveexplained. Manifestly a solid back jaw might be employed inconnection-with that construction, if so desired. However, when theswiveled jaw is employed it is sometimes desirable to fix it securely ina position with its face parallel with that of the frontjaw, so that itwill not yield in either direction when any article is clamped betweenthe two jaws.

D is a depending portion of the vise-jaw D, which rides in a recess inthe upper part and at the back of the vise-body. In connection with thisdepending portion D', I employ a screw D2,which enters a recess in thepart D. This screw passes through an opening provided for it at the backof the vise-body, and it has a conical projection D3, which fits aconical recess in the opening through the back of the vise-body. rIheconical projection D3 is of such length that when the screw D2 iscompletel y unturned to release the depending portion D then the conicalportion and the threaded end of the screw will be located in the openingthrough the vise-body, leaving the vise-jaw free toturn upon its seat inthe manner then' intended. Vhen the screw D2 is turned in in the mannershown in the drawin the conical recess provided for its reception,

and therefore prevents the screw from moving in its seat, andconsequently prevents the vise-jaw from 'moving in any degree. Theconstruction and arrangement being substantially as indicated, theswiveled jaw may be rigidly set at the desired point and releasedwhenever required. rIhe screw D2 is pre vented from becoming dislodgedby the application to the exterior of the vise-body of a recessed plateD4, which is screwed in place, as indicated, or secured in any otherdesirable manner.

c The improvements, being constructed and arranged for operationsubstantially in accordance with the foregoing explanations, will befound to admirably answer all the purposes or objects of the inventionhereinbefore alluded to.

Having now fully described my invention, what I claim as new herein, anddesire to secure by Letters Patent, is-
